Semperton Multibase
Base transcoder with multibyte character alphabet support.
Installation
Just use Composer:
composer require semperton/multibase
Multibase requires PHP 7.4+ and the mbstring extension
Tip: Install the GMP extension for faster base conversion up to base 62
Package
Included base transcoders:
- Base58
- Base62
- Base85 RFC 1924
Usage
Multibase transcoders are able to convert any arbitrary data. Use them as URL / MD5 shorteners, password generators, Base64 alternatives...
use Semperton\Multibase\Base62;
use Semperton\Multibase\Base85;
// basic usage
$base62 = new Base62();
$base62->encode('Hello World'); // 73XpUgyMwkGr29M
$base62->decode('73XpUgyMwkGr29M'); // Hello World
// shorten md5 hash
$hash = md5('Hello World'); // b10a8db164e0754105b7a99be72e3fe5
$short = $base62->encode(hex2bin($hash)); // 5O4SoozqXEOwlYtvkC5zkr
$short = $base62->encode(md5('Hello World', true)); // same as above
$decoded = $base62->decode($short);
$hash === bin2hex($decoded); // true
// password generation
$bytes = openssl_random_pseudo_bytes(16);
$password = (new Base85())->encode($bytes); // e.g. Ncg>RWSYO+2t@~G8PO0JCustom transcoders
You can create custom transcoders with your own alphabets (multibyte support). Just for fun, how about an emoji transcoder?
use Semperton\Multibase\Transcoder\BaseTranscoder;
$emojiTranscoder = new BaseTranscoder(
'π§³πβοΈπ§΅πͺ‘πͺ’π§ΆππΆπ₯½π₯Όπ¦Ίππππ§£π§€π§₯π§¦πππ₯»π©΄π©±π©²' .
'π©³πππππππππ₯Ύπ₯Ώπ π‘π©°π’πππ©ππ§’βπͺπππΌ'
);
$encoded = $emojiTranscoder->encode('Hello World'); // βπͺ’ππ©΄π©°π₯»πππ§’π©²π§₯π₯½π©πππ
$emojiTranscoder->decode($encoded); // Hello World
